If 1 mistake not, the Chlorostilbon Osherti will be found to range over a very considerable extent of country ; in all probability from Panama to Guatemala. I have named this bird in honour of Mr. Osbert Salvin, a gentleman who has so praiseworthily exerted himself to make us more intim itely acquainted with the birds of Guatemala, and whose notes referring to this species, which I give below, brief though they be, will be of interest :— “A pair of this species resort to the flowers about our house at Duenas. “One specimen was shot on the Volcan de Fuego, at an altitude of about 5000 feet above the sea-level, the highest altitude at which I have yet observed tt. « Duri eastern side of the lake.” ; sci hie eae ee In speaking of the brilliant colouring of the bills of another species of Humming-Bird, Mr. Salvin remarks, ig the months of August and September this species may be found among the trees on the south- ; arency of the ar fi * the bill allowine the “T may mention that it appears to be due to the transparency of the outer film of the f ing blood * show through, and not to any especial colouring-matter.
